Foreign-Owned Single-Member LLC Filing Requirements

Being the sole owner of a US LLC as a non-US resident puts you in a unique category with the IRS. Because you don't have partners, you skip partnership tax returns. However, you are targeted by the IRS's strictest anti-money laundering regulations.

Quick Answer

A foreign-owned Single-Member LLC is treated as a "Disregarded Entity" for income taxes, but as a "Corporation" for informational reporting. Every year, you must file Form 5472 and a Pro Forma Form 1120 by April 15th to report money moving between you and the LLC. Failing to do so triggers a $25,000 penalty.

Key Points for 2026

Informational vs Tax: Form 5472 does not calculate tax; it simply reports transactions to the IRS.
FBAR Exemption: Foreign owners of US bank accounts generally do not have to file FBARs.
The 1040-NR Trigger: You only file a personal US tax return if your LLC is engaged in a US trade or business and generates ECI.

The Annual Filing Checklist

If you own a Single-Member LLC and live outside the US, this is your annual checklist:

1. IRS Form 5472 & Pro Forma 1120

Due: April 15th (can be extended to October 15th).

This is mandatory if any "reportable transactions" occurred (e.g., you deposited money into the business bank account, or the business paid you). Because almost all active LLCs have transactions, this is practically mandatory for everyone.

2. IRS Form 1040-NR (If Applicable)

Due: April 15th (can be extended to October 15th).

You only file this if your LLC has Effectively Connected Income (ECI)—for example, if you sell physical goods stored in a US Amazon warehouse. If you just sell digital goods from your laptop in Europe, you usually do not file this.

3. State Annual Report

Due: Varies by state (e.g., June 1st in Delaware, First day of your anniversary month in Wyoming).

You must pay a fee to your state of formation every year to keep the LLC alive. This is separate from the IRS.

4. BOI Report (FinCEN)

Due: Within 90 days of formation (or by Jan 1, 2025 for older LLCs).

Under the Corporate Transparency Act, you must report the identities of the LLC's beneficial owners (you) to FinCEN. This is a one-time filing unless your address or passport changes.

The Disregarded Entity Confusion

Many foreign founders read that a Single-Member LLC is a "Disregarded Entity" and incorrectly assume the IRS completely ignores the LLC. The IRS ignores the LLC for income tax calculations, but it explicitly targets the LLC for informational reporting via Form 5472.

Single-Member Filing FAQs

Does my Single-Member LLC pay corporate tax?

No. A Single-Member LLC is a 'disregarded entity.' It does not pay corporate income tax. Any tax owed is passed through to you, the individual owner.

Do I have to file Form 1040-NR?

You only file a non-resident personal tax return (1040-NR) if you generated Effectively Connected Income (ECI) from a US trade or business. If you just sold software from overseas, you likely do not need to file a 1040-NR.

Are there state filing requirements?

Yes! The IRS requirements are federal. You must also file an Annual Report and pay franchise taxes to the state where you formed the LLC (e.g., Delaware or Wyoming).

What is FBAR, and do I file it?

If you own a US LLC with a US bank account, the LLC itself generally does not file an FBAR. FBARs are for US persons with foreign bank accounts, not foreign persons with US bank accounts.
